A new Victoria's Secret ad abuses an apostrophe, but unfortunately, it's a common error. Here's the scoop on when to use apostrophes to make things plural. (Hint: Almost never.)
A Caveat: The Quotation Marks
I would be remiss if I didn't point out that Victoria's Secret put "Body's" in quotation marks. Why is that important? Because quotation marks can be used to highlight words that are used in odd or nonstandard ways. The Chicago Manual of Style calls them scare quotes. Therefore, the quotation marks could be considered something of a wink: as if they're saying, "We know we formatted this wrong."
How Could They Fix It?
The frustrating thing to me though, is that they could have easily avoided the problem by using typography instead of punctuation. Because "Body" is a brand name, the correct plural is "Bodys." They could have made the B-O-D-Y big and the S at the end small, and still preserved their brand name while formatting the plural correctly. It was the same frustration I had with the Mercedes ad that talked about "less doors" a few years ago, which they could have easily fixed by treating "door" as a concept and saying "less door" the same way you might talk about a woman showing less leg.
But maybe they just don't care. Victoria's Secret is actually a repeat punctuation and grammar offender. A couple of years ago, they ran an ad that said "There's 5 ways," which is short for "There is 5 ways," which is obviously wrong. It's a common error in speech, but less common in print.
